Szív City is a free iPhone application developed by Alerant Informatikai Zrt. It aims to provide assistance in the event of a heart attack by utilizing the capabilities of smartphones for location tracking and navigation. Specifically designed for densely populated areas, Szív City supports pedestrian assistance by connecting individuals in close proximity who are trained in first aid and can provide life-saving assistance before medical professionals arrive.

To use the application, users need to register and only logged-in users have access to its features. Upon first launch, you will be prompted to register on the opening screen if you do not already have a Szív City account. After registration, it is recommended to keep the application running in the background to receive notifications about nearby emergencies.

Szív City requires mobile internet and location services to function properly. Location tracking is necessary to identify individuals near an emergency event, so it is important to grant the application access to location services even when not actively using it on your iPhone.
